A highly efficient method for the synthesis of medium-sized lactams based on intramolecular Staudinger–aza-Wittig reaction of ω-azido pentafluorophenyl ester has been developed. A variety of 7–10 membered lactams were synthesized in excellent yields. Application of the method to the synthesis of analogues of a potent γ-secretase inhibitor LY411575 and their biological evaluation are also described
已经开发了一种基于ω-叠氮基五氟苯基酯的分子内Staudinger-aza-Wittig反应的中型内酰胺合成的高效方法。合成了多种7-10元内酰胺,收率很高。还描述了该方法在有效的γ-分泌酶抑制剂LY411575的类似物的合成中的应用及其生物学评价。
